nutrition Flashcards
(40 cards)
nutritional requirements must be met for
- essential nutrients must be replaced for loss and to allow the growth of new tissues
- energy to permit metabolic functions
- maintenance, growth and development
- development of immunity
Phases of child growth
- infancy= nutrition led
- childhood= growth hormone led
- pubertal= sex steroid led
EAR stands for
estimated average requirement which means 50% of the population will need more than this value and 50% of the population will need less than this value
RNI stands for
recommended nutritional intake and it is 2 standard deviations above the estimated average requirements and is sufficient for 97% of the population
LRNI stands for
lower reference nutritional intake and it is 2 standard deviations below the estimated average requirement and it is only sufficient for 3% of the population who have the lowest needs
protein
reference nutrient intake is 12.7 to 14.5g per day for infants aged 4-18 months)
energy reference values between 0-12 months
takes into account the energy deposited in new tissue plus the total energy expenditure
energy reference values between 1-18 years
takes into account
- total energy expenditure and deposited energy costs: basal metabolic rate x physical activity level
- estimated average requirement calculated at median physical activity level values for best estimated of healthy body weight
majority of children
exceed their estimated average requirement for energy
Vitamins
Vitamin A, C and D
vitamin A
RNI is 350-400 micrograms/day
dietary sources of vitamin A
cheese, egg and yoghurts
dietary intake of vitamin A
is greater than the RNI for all age groups
vitamin C
RNI is 25-30 miligrams per day
dietary sources of vitamin C
oranges, blackcurrant and potatoes
dietary intake of vitamin C
is greater than the RNI for all age groups
vitamin D
RNI is 7-8.5 micrograms per day
sources of vitamin D
main source is from sunlight but a small amount comes from oily fish and eggs
vitamin D intake is
below the RNI for all breastfed infants of all age groups and below the RNI for non-breastfed infant aged 12-18 months
vitamin supplements
- from 6 months infants who are not consuming at least 500mls/day of infant formula should take VITAMIN A,C AND D supplements
- breast feeding mothers should take vitamin D supplements of 10 micrograms per day
sodium RNI
aged 4-6 months= 280mg
aged 7-9 months= 320mg
aged 10-11 months= 350mg
aged 12-18 months= 500mg
1g of salt contains
393mg of sodium
sodium intake
exceeds the RNI for all age groups except for the 4-6 months
minerals are
iron and calcium
